Reena Kwong

Reena Kwong was an ES Cornwall Scholar for a period commencing March 2009 through until November 2010 - during which time Reena worked with National Grid (in the UK) and the Ontario Power Authority (in Canada).

This presentation was prepared in April 2011, following my return to Australia after my stint overseas on the scholarship.

It provides a summary of my experience – both with National Grid (in the UK) and the Ontario Power Authority (OPA) (in Canada).

Through my scholarship, I did achieve my objective of understanding more about the operational and planning approaches used in the integration of large-scale renewable energy into large, established electricity grids.

This post marks my 6th quarterly term overseas as part of my E.S. Cornwall Memorial Scholarship.

Work on integrated regional area planning was also a focus during my time at the Ontario Power Authority (OPA) due to the announcement of the Long Term Energy Plan being released by the government.

As well as outlining my work during the second half of my year at the OPA, this report also provides a summary of my scholarship tenure whilst working at National Grid and in Ontario with the OPA in terms of renewable energy integration.

Following 12 months in the UK with National Grid, I flew to Canada for the 2nd placement as part of my scholarship.

For the period 8th March to 8th June 2010 I was employed with the Ontario Power Authority (OPA) in Toronto, Canada.

As this is my first report during my placement with the OPA, I have provided some background on the electricity system in Ontario as well as an overview of the OPA; its roles and responsibilities as well as its increased involvement with renewable generation integration due to recent changes introduced by the Ontario government which have impacted the procurement and planning of renewable generation.

I also provide some discussion on my initial experiences in learning about, and addressing, factors hindering the connection of large and small scale renewable projects due to current transmission and/or distribution capability limitations.

As this is my final report during my year-long placement with National Grid, I have provided a general overview on the insight I have gained over the past year on the planning and operational areas that National Grid are concerned with due to the integration of large volumes of wind generation.

My third quarter with National Grid (following my experiences in the 1st and 2nd quarters) enabled me to progress deeper into the modelling of the potential impact of wind on the transmission system under various scenarios.

During my third term with National Grid (through until December 2009), I have been involved in AC power system studies focussing on voltage and thermal compliance of the Great Britain network with the addition of proposed wind generation in order for GB to achieve the UK renewable target by 2020.

These studies investigate the planning and operational design of the network required to accommodate larger volumes of generation in certain areas, and also the possible solutions to network issues should they arise due to the additional generation.

Following from my first three months (discussed here), I continued into my second quarter, remaining with National Grid, and continuing to gain experience in renewable energy generation.

During this term, I have been able to gain an insight into the “Power Factory” analysis package for which loadflow results are to be used to facilitate the evaluation of the wide range of possible generation scenarios on required transmission capacity in the Great Britain network.

As part of the Power Factory work, I have obtained some experience in modelling the Great Britain network with the appropriate generation and demand scenarios in preparation to obtain more detailed results from voltage and transient stability analyses.

My scholarship commenced in March 2009, when I was employed by National Grid, the transmission system owner and operator in the UK.

During the first 3 months of my placement I worked with the “Strategy Review Team” and have been able to obtain some insight into various types of transmission reinforcements which may be used in order to improve network capability for the integration of large volumes of renewable generation.

I performed system studies implementing these reinforcements to determine the extent of their impact on the network.
